David Hildenbrand b3c395ef55 mm/uaccess, mm/fault: Clarify that uaccess may only sleep if pagefaults are enabled 
In general, non-atomic variants of user access functions must not sleep
if pagefaults are disabled.

Let's update all relevant comments in uaccess code. This also reflects
the might_sleep() checks in might_fault().
